*From the above example, there is a minor collection and one full collection.
*The GC 66693K->60776K is the combined size of live objects before and after garbage collection respectively.
*The 88216K is the total available space – in other words to total heap.
*The 0.0128313 secs is the amount of time it took to perform a minor collection.

There are a number of tuning options available to assist with performance related issues. Here are a few of those options, for a complete list of all the java options, please refer to the Java Virtual Machine Garbage Collection Tuning document.

*(-XX:+UseParallelGC -XX:ParallelGCThreads=2)
__(-XX:+UseParallelGC -XX:ParallelGCThreads=2)__\\The parallel collector is the default collector on server class machines. Increase the parallel GC threads to match the CPU count. The above example implies the server has two CPUs.

__(-XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode)__\\The above options will enable the concurrent collector. The concurrent collector will shorten pause times by sharing processor resources with the garbage collector while the application is running. This option should only be used on server class machine that have more than 2 CPUs.

!Self-Service Timeout
The timeout setting for Self-Service will have a negative impact on performance if it is not configured correctly. By default, the web server sessions will remain for 30 minutes before they're removed. If the server has limited resources this can be an area where resources can be reclaimed.
